Homebase is offering customers the chance to win 100,000 Nectar points if they submit an online review of a product purchased at the retailer.
Those who submit a review will be entered into a monthly prize draw to win the points, worth £500.
A statement on the Nectar page of Homebase's website reads: "Your feedback is valuable as it helps us to provide you with the ideal products to suit your requirements, to improve and maintain the excellent service we offer and also allows other Homebase shoppers to benefit from your experience."
The details of the prize draw were also emailed to customers, showing them their recent purchases and offering them a chance to review the products.
